(D) Flap Flipping and Suturing (Central). Supplementary Figure 2. Case 7 with Faultage Matrix Flipped Flap reconstruction for the treatment of longitudinal melanonychia (LM). (A). LM on the fingernail. (B). excise the lesion. (C). Reflect the flap and invert to cover the defect. (D). Closure was achieved with 6-0 polypropylene sutures. (E). restore the appearance. (F). Postoperative outcomes demonstrating no recurrence of melanonychia or nail dystrophy in the reconstructed fingernail at 19-month postoperative follow-up. Supplementary Figure 3. Case 8 with Faultage Matrix Flipped Flap reconstruction for the treatment of longitudinal melanonychia (LM). (A). LM on the fingernail. (B). Intraoperative findings revealed the pigment involved both the nail matrix and the nail bed. (C). excise the lesion. (D). Reflect the flap and invert to cover the defect, then closure was achieved with 6-0 polypropylene sutures. (E). Postoperative outcomes demonstrating no recurrence of melanonychia or nail dystrophy in the reconstructed fingernail at 15-month postoperative follow-up. Supplementary Figure 4. Case 9 with Faultage Matrix Flipped Flap reconstruction for the treatment of longitudinal melanonychia (LM). (A). LM on the fingernail. (B). Intraoperative findings revealed the pigment involved both the nail matrix and the nail bed. (C). excise the lesion. (D). Reflect the flap and invert to cover the defect, then closure was achieved with 6-0 polypropylene sutures. (E). Postoperative outcomes demonstrating no recurrence of melanonychia or nail dystrophy in the reconstructed fingernail at 14-month postoperative follow-up. Supplementary Figure 5. Case 14 with Faultage Matrix Flipped Flap reconstruction for the treatment of longitudinal melanonychia (LM). (A). LM on the fingernail. (B). excise the lesion. (C). Reflect the flap and invert to cover the defect. (D). Closure was achieved with 6-0 polypropylene sutures. (E). Reattach the avulsed fingernail plate to its anatomical position using absorbable sutures. (F). at 5-month postoperative follow-up. (G). at 7-month postoperative follow-up. (H). at 8-month postoperative follow-up. (I). at 9-month postoperative follow-up. (J). at 14-month postoperative follow-up. Supplementary Table 1. Patients’ demographic and clinical characteristics.
